HMUD Data Manual

V 1.0

HMUD is a software package to allow NHS staff access to hospital medicines utilisation data. The HMUD database is based on data extracted from hospital pharmacy systems around Scotland.

The data used from hospital pharmacy systems comprises of issues to clinical areas for end patient use, and therefore HMUD does not contain information on all medicines purchased by the hospital pharmacy.

These data are augmented with information on occupied bed days, patient numbers and episodes, to provide additional denominator data.

Crucially, however, with all the data it contains, HMUD does not have data on actual clinical usage or the patients the medicines are used in.

The volumes of data involved in HMUD can be enormous. For efficiency purposes, therefore, a number of aggregate tables have also been produced containing summary statistics for ease and speed of reference.

The HMUD Data Manual is designed to be a concise and user-friendly guide to the definition, interpretation and coding of key data items found in the HMUD WebIntelligence Universe.

The manual is organised into chapters, each representing a ‘class in the HMUD universe. Key data items in each class appear together with a definition for the item, any coding schemes used, and advice on interpretation (where relevant).

1.1 Data Universe A universe is a representation of the information available in a database.

It is the entire collection of objects and classes that are available to the user for defining their own reports.

1.2 Data Objects An object is an element in the universe and relates to data in a database. You use objects to retrieve data for your reports.

There are three types of object in the HMUD Universe:

Dimension Objects They are denoted by a small blue cube, as shown below:

It is very likely that the queries you build/create will be based around dimension objects - they provide the basis for analysis in a report. Examples of dimension objects are Health Board Code, Location Short Name, and Chapter BNF Description.

Measure Objects A purple sphere, as shown below, denotes a measure object:

A measure object always contains numeric data. The value a numeric object returns varies depending on the dimension object with which it is used. An example best illustrates this:

If you include Location Short Name as the dimension object, and Cost as the measure object in a query, this would return the costs for medicines issued for each hospital included in your query.

However if you include Health Board Name as the dimension object and Cost as the measure object in a query, this would return the costs for each NHS Board included in your query.

Filter Objects For many ad-hoc queries, you will only be interested in a small section of the data that could be returned. For example, you may wish to find the total quantity of drugs dispensed but only for a specific BNF chapter. A filter is used to limit the results of a query to the section of data that the user is interested in, in this case, a specific BNF chapter.

You can use any dimension object such as Health Board Name or BNF Section Code as a filter. HMUD also provides a number of pre-defined filters for items that are likely to be used most frequently.

Pre-defined filters are denoted by a small yellow funnel:

Nearly all of the pre-defined filter objects are contained within the Time Class.

1.3 Classes and Sub-Classes The purpose of classes is to provide logical groupings of data objects. When you create queries on the universe, classes help you to find the objects that represent the information that you want to use in a query. A particular class can consist of a number of sub-classes.

In HMUD, an example of a class is Medicines, which includes the subclasses BNF, DMD and Formulary Status .

2 Organisation Details Class

The Sub-Classes contained within the Organisation Details Class provide dimension objects for all of the organisational levels which can be queried within HMUD.

2.1 NHS Board Sub-Class This class contains data objects pertaining to NHS Boards.

2.1.1 Health Board Code

Single-character cipher, identifying an NHS Board (formerly known as Health Board). These are detailed below:

Health Board Code Health Board Name A NHS AYRSHIRE & ARRAN B NHS BORDERS E* ENGLAND HEALTH BOARD F NHS FIFE G NHS GREATER GLASGOW & CLYDE H NHS HIGHLAND L NHS LANARKSHIRE N NHS GRAMPIAN R NHS ORKNEY S NHS LOTHIAN T NHS TAYSIDE U* UNKNOWN HEALTH BOARD V NHS FORTH VALLEY W NHS WESTERN ISLES x** NATIONAL FACILITY

x** NHS24 x** NHS EDUCATION FOR SCOTLAND x** NHS HEALTH SCOTLAND x** NHS QUALITY IMPROVEMENT SCOTLAND x** SCOTTISH AMBULANCE SERVICE x** STATE HOSPITAL x** UNKNOWN HEALTH BOARD EX A&C X* DUMMY SCOTLAND HB Y NHS DUMFRIES & GALLOWAY Z NHS SHETLAND

Notes: * This is the complete reference listing held by ISD, however, since data is extracted from specific NHS Boards, ciphers E, U and X will not return any data in HMUD. ** This Health Board code covers a number of national bodies, however, "National Facility", is the national waiting times centre at the Golden Jubilee Hospital is the only location which will supply data to HMUD. Therefore the use of Code "x" will return data for the Golden Jubilee Hospital only.

2.1.2 Health Board Name

The name of the NHS Board area where medicines are prescribed. See Health Board Code for further details.

2.2 Cancer Network Sub-Class This class contains data objects pertaining to Cancer Networks.

Cancer networks can be defined as "Managed Clinical Networks where linked groups of health professionals and organisations from primary, secondary and tertiary care, work in a co-ordinated manner, unconstrained by existing professional and Health Board boundaries, to ensure equitable provision of high quality clinically effective services".

Within Scotland (and therefore, within HMUD) there are three Cancer Networks, each containing a number of NHS Boards.

2.2.1 Cancer Network Code

The identifier code for the cancer network

Cancer Network Code Cancer Network Name Health Board Name NoSCAN NORTH OF SCOTLAND NHS Highland NoSCAN NORTH OF SCOTLAND NHS Grampian NoSCAN NORTH OF SCOTLAND NHS Orkney NoSCAN NORTH OF SCOTLAND NHS Tayside NoSCAN NORTH OF SCOTLAND NHS Western Isles NoSCAN NORTH OF SCOTLAND NHS Shetland

SCAN SOUTH EAST SCOTLAND NHS Borders SCAN SOUTH EAST SCOTLAND NHS Fife SCAN SOUTH EAST SCOTLAND NHS Lothian SCAN SOUTH EAST SCOTLAND NHS Dumfries & Galloway WoSCAN WEST OF SCOTLAND NHS Ayrshire & Arran WoSCAN WEST OF SCOTLAND NHS Greater Glasgow & Clyde WoSCAN WEST OF SCOTLAND NHS Lanarkshire WoSCAN WEST OF SCOTLAND NHS Forth Valley

2.2.2 Cancer Network Name

The name of the cancer network. See Cancer Network Code for details.

2.3 Location Details Sub-Class This class contains data objects pertaining to Hospital Locations.

2.3.1 Location Code

The location code. This is comprised of a 5 character alphanumeric code:

Character 1 (alpha) specifies the NHS Board Areas Characters 2-4 (numeric) is a unique code for each location in the NHS Board Character 5 (alpha) specifies the type of location.

In HMUD data are restricted to NHS hospital-based locations, therefore character 5 of the location code will always be H. See below for some examples

HB Code Location Location Short Name Code F F701H CAMERON HOSPITAL F F709H ST ANDREWS MEMORIAL HOSPITAL F F805H QUEEN MARGARET HOSPITAL S S305H ST MICHAEL'S HOSPITAL S S306H TIPPETHILL HOSPITAL S S308H ST JOHN'S HOSPITAL

2.3.2 Location Short Name

The name of the location e.g. St John's Hospital

For more examples see Location Code.

2.3.3 Location Full Description

The Location Full Description provides an alternative, often fuller location name.

HB Code Location Location Full Description Code F F701H CAMERON HOSPITAL, LEVEN, FIFE F F709H ST ANDREWS MEMORIAL HOSPITAL F F805H QUEEN MARGARET HOSPITAL, DUNFERMLINE

S S305H ST MICHAEL'S HOSPITAL, LINLITHGOW S S306H TIPPETHILL HOSPITAL, WHITBURN S S308H ST JOHN'S HOSPITAL AT HOWDEN, LIVINGSTON

2.3.4 Location Classification Code

This code does not represent the Costs Book Classification of hospitals, but uses a "peer group" classification system to group hospitals for comparison purposes within the standard reports. Whilst the codes remain the same as the Cost Book, the actual hospitals contained in the group may differ from the Cost Book.

This "peer group" classification is used in other ISD data products such as "Navigator"

Main CategorySub Description Category A General Hospitals (mainly acute) 1 Teaching hospitals - major teaching hospitals covering a full range of services and with special units. 2 Large general hospitals - general hospitals with some teaching units, usually over 250 average staffed beds. 3 General hospitals - mixed specialist hospitals (may have maternity units). Consultant type surgery undertaken, usually 250 and under average staffed beds. 4 Sick children's hospitals - large teaching hospitals for children covering a range of medicine and surgery. 5 Community hospitals - general practitioner hospitals (may have maternity unit) and visiting consultant clinics but no surgery. B Long Stay Hospitals 6 Long stay hospitals (over 100 average staffed beds) - long stay geriatric units controlled by geriatrician. May be with young chronic sick unit. 7 Small long stay hospitals (100 and under average staffed beds) - long stay geriatric units controlled by geriatrician. May be with young chronic sick unit. 8 Long stay/acute hospitals - long stay geriatric units with some medical and surgical services. 9 Long stay/psychiatric hospitals - long stay geriatric units with geriatric psychiatry. 10 Long stay/community hospitals - general practitioner hospitals with some long stay cases. 11 Geriatric day hospitals. C Mental Hospitals 12 Teaching mental illness hospitals with major teaching or research units. 13 Large mental illness hospitals with over 250 average staffed beds, may have some teaching element. 14 Mental illness hospitals with 250 and under average staffed beds. 15 Mental illness day hospitals. D Psychiatry of Learning Disabilities Hospitals 16 Large learning disabilities hospitals (over 150 average staffed beds). 17 Learning disabilities hospitals (150 and under average

staffed beds). 18 Learning disabilities day hospitals. E 19 Maternity Hospitals F 20 Dental Hospitals G Other 21 Other: Miscellaneous hospitals in which function and/or costs are not comparable with other hospitals. 22 Other: New/Closed Locations - Hospitals subject to cost but in the process of retraction or closure (may include new hospitals with costs for part year). 23 Other: Shared Facilities - Hospitals with beds managed by more than one trust - that part of the hospital not managed by the 'parent' trust and with costs not comparable to other hospitals. H Clinics 24 Hospital Clinics 25 Non-Hospital Clinics

The code for each hospital type are therefore held as e.g. A1, A2...,B6, B7, etc.

2.3.5 Location Classification Description

Description based on concatenation of main category description and sub-category description. See Location Classification Code for examples

2.3.6 Location Classification Main Category Code

The main cost book classification code.

Examples:

Main Description Category A General Hospitals (mainly acute) B Long Stay Hospitals C Mental Hospitals D Psychiatry of Learning Disabilities Hospitals E Maternity Hospitals F Dental Hospitals G Other H Clinics

2.3.7 Location Classification Main Category Desscription

The description of the cost book main category e.g. General Hospital etc.

For more details see Location Classification Main Category Code.

All of the objects in the time class are associated with the segmentation and labeling of time periods.

Some of the time objects are pre-built filter objects which generate prompts for the user to respond to, however, some of the dimension objects can also be used as query filters.

3.1 Financial Month Financial month number and abbreviated month name, detailed below.

01 (Apr) 02 (May) 03 (Jun) 04 (Jul) 05 (Aug) 06 (Sep) 07 (Oct) 08 (Nov) 09 (Dec) 10 (Jan) 11 (Feb) 12 (Mar)

3.2 Financial Quarter Financial quarter in the format detailed below.

1 (Apr-Jun) 2 (Jul-Sep) 3 (Oct-Dec) 4 (Jan-Mar)

3.3 Financial Year Financial year in format 'yyyy/yy' (e.g. 2003/04).

Notes: 1. When using this object as a Query Filter, there will be more years listed than are available in HMUD. Therefore, careful selection of the financial years required is important - selecting financial years for which there is no data will return only a blank report.

2. HMUD will eventually contain up to 60 months of data i.e. 5 years. However, as this is updated monthly, there will be times when there are six financial years in the system - only the middle 4 years will be complete, the oldest and most recent years will be incomplete.

3.4 Financial Year Quarter The financial year and quarter combined into a single object with format yyyy/yy Qn where n represents the quarter e.g. 2003/04 Q2 represents the second quarter of the financial year 2003/04 i.e. July to September 2003.

Notes: 1. It is recommended that this object is not used as a filter for performance reasons.

2. When using this object as a Query Filter, there will be more year/quarters listed than are available in HMUD. Therefore, careful selection of the time periods required is important - selecting time periods for which there is no data will return only a blank report.

3.5 Calendar Dates Sub-Class These objects allow the use of calendar dates rather than financial ones. Some users find it preferrable to include calendar rather than financial time periods in reports for ease of reading.

3.5.1 Calendar Month

Calendar month number and abbreviated month name, detailed below,

01 (Jan) 02 (Feb) 03 (Mar) 04 (Apr) 05 (May) 06 (Jun) 07 (Jul) 08 (Aug) 09 (Sep) 10 (Oct) 11 (Nov) 12 (Dec)

3.5.2 Calendar Quarter

Calendar quarter in the format detailed below.

1 (Jan-Mar) 2 (Apr-Jun) 3 (Jul-Sep) 4 (Oct-Dec)

3.5.3 Calendar Year

The Calendar Year in the format yyyy (e.g. 2003).

Notes: 1. When using this object as a Query Filter, there will be more years listed than are

available in HMUD. Therefore, careful selection of the time period required is important - selecting years for which there is no data will return only a blank report.

2. HMUD will eventually contain up to 60 months of data i.e. 5 years. However, as this is updated monthly, there will be times when there are six years in the system - only the middle 4 years will be complete, the oldest and most recent years will be incomplete.

3.5.4 Calendar Year Quarter

The calendar year and quarter combined into a single object with format yyyy Qn where n represents the quarter e.g. 2005 Q2 represents the second quarter of the calendar year 2005 i.e. April to June 2005.

Notes: 1. It is recommended that this object is not used as a filter for performance reasons.

3.5.5 Latest Calendar Year

This object is a pre-built filter which provides the latest complete calendar year available.
